Just found that on the Donek's FB page (sorry if you don't have FB...)



That's brilliant !

What's with all the extra holes in the core?

Race board? Plate bindings maybe

Even better I have seen a surface planer that was modified to just auto feed the cores over torches. Both sidewalls got flamed in one pass. Pretty slick but you had to keep an eye on it to make sure it kept feeding.

Cool but seems like a lot if work for a pretty simple task...?

How many passes with a propane torch do you guys use?

I typically do 6-8 quick passes (~1ft/sec) over each sidewall surface. I do a basic water drop test and observe changes in the drop shape after every 2 passes. Once the drop flattens out to where it looks similar to a drop placed on the wood I stop.

I basically do two passes... once in each direction, a little slower than you do. I agree, this is a clever rig, but it still relies on the human to have a good rate. Just ensures consistent positioning.

Still, I'm all for homemade things like this. I've certainly made more complicated things that did simpler jobs, worse

Why dont you mount a torch on the CNC. Mach has a torch on off function. Now that i think about it a computer controlled flame thrower on a saw dust covered machine might not be the best idea.

That Mach setting is for a plasma cutter. Mounting a propane trove on a CNC to flame treat sidewalls would be just a bit of overkill.

What about sanding do you guys sand or put a texture on before flaming after flaming or not at all?

Abrade before flaming.

1. Flaming removes some of the micro hairs

2. You want to flame treat the structure you just put into the material

great flame job there guy, but the ungloved hands are killing it
